> It appears that even though incremental repair is now enabled by default post C*-3.0 (which means at the end of each repair session, there is an anti-compaction step that needs to be executed), we don't include the parent repair session UUID in the log message of the anti-compaction log entries. This makes observing all activities related to an incremental repair session to be more difficult. See the following:

> The initial submission of the anti-compaction task to the CompactionManager still has reference to the parent repair session UUID, but subsequent anti-compaction log entries are missing this parent repair session UUID.
